Application filed January 19', 1925. serial m. 3,531.

To all whom it may concern Be it known that I, CORNELIA L. HAENS- sum, citizen of Germany, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Immovements in'Door Safety De-- 15 shelf which may be utilized as a resting.

lace for receipts or the like whichv are to )6 signed.

The invention has for an object the provision of a novel arrangement of parts as above set forth, with which is combined a metal outside frame that normally closes the panel opening in the door.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended clalms m wh ch the various novel features of the .inventlon are more particularly set forth.

Fig. 1 of the drawing is a face new of a door having the invention embodled thereln.

Fig. 2 is a artial transverse vertical sectional view ta en on the line 2-2 of Fig. 1.

Fig. 3- is afragmentary face view on a larger scale than Fig. 1. r

Fig. 4 is a; detail horizontal secltlonal view taken on the line 4-4 of Fig. 3..

In the drawing the reference numeral indicates an ordinary door such a's'ls pro vid'ed for entrance.to houses or apartments. In the upper portion of this door a rectangular opening 11 is cut. This open ng is closed by, a swingable member comprising a glass panel 12 set in a frame element 1.3, and which is hinged at its lower edge as at 14 to the door to swing downwardly and inwardly. As will be apparent, the. glass panel 12 presents the usual appearance of a glass pane in the door. The sw ngable member is retained in closed position by means of a button 15 mounted on the inner face of the door above the said member-and adapted to detachably engage the top edge thereof. F ixed at one end to a staple 18 approximately horizontal on the door and edits other end to another staple 19 on the frame 13, is a chain 20 which serves to support the said swingable member in the horizontal lowered position shown in dot-ted lines in Fig. 2 of the drawing.

Extending across the opening 11, in front of the said swingable glass panel member, is a frame consisting of a number .of vertical bars 22 that are attached atthe upper and lower ends to the horizontal bars 23, 24.

This frame may be arranged to swing inwardly upon the glass panel member when it is desired to receive parcels of any considerable size through the opening in the door. To this end the lower bar 24 has its ends pi'votally engaged in bearing elements 25 on the door. The frame is locked in upright position by means of a locking bolt 27 that is slidable in a horizontal tubular element 28 I on the frame and which engages in a keeper member 29 on the door, outward swinging movement of the frame being limited by means of a projection 30 on the top bar 23 of the frame that engages behind a lip 31 on the top wall of the door opening 11.

This bolt 27 also passes through an aperture 32in the lower end of a rigid link or arm 33 that is pivotally attached at its. upper end to the side bar of the frame as at 34,

thereby holding the link alined with the'said' side bar. The link 33 has attached to its lower end one end of a second chain-35 whose other end is attached to a staple 36 on the side wall of the door opening 11. The parts are so-proportioned that when the frame is swung mward,-withthe rigid link 33 with relation to the frame. the latter will only swing inward a relatively short distance,

while if the link is freed to swing with the chain 35 the frame can be swung inward to position. For manipulating the bolt 27'the latter has attached thereto a stud 38 that projects through a slot 39 in the tubular member 28, this-slot having an offset extension 39 that receives the stud when the bolt is to be withdrawn sufficiently to disengage from the link 33, the shoulder 39at the entrance to this slot extension normally limiting the movement of the bolt before such' disen agement 'occurs. If desired I may provi e on the rear face of the door a hinged shutter frame 42 that ma be swung upward when desired behind't e glass panel.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the'llnited States is as follows 1. In combination with a door, a transparent panel member hinged to said door in tin opening therein to swing downwardly and inwardly, and a barred frame extending across the said opening in front of the said panel member, said framebeing hinged at nits lower edge to the door to swing inwardly through the said opening, a link pivoted at *its'a mper end to the side of the said frame,

a chain attached at one end to the door and at its other end to the link, and a locking bolt carried "by said frame and adapted to engage the said door to retain the framein upright position, said locking bolt passing through an aperture in the said link to retain the latter in position lying along the said frame, to limit the inward swinging movement of the. frame.

2. In combination with a door. a trans-.

through the said opening, a link pivoted at its upper end to the side of the said frame, achain attached at one end to the door and at its other end to the link, and a locking bolt mamas carried by said frame and adapted to engage the said door to retain the frame in upright position, said locking bolt passing through an aperture in the said link to retain the latter in'position lying along the said frame, to limit the inward swinging movement of the frame, and said locking bolt slidably freeable from said aperture of said link allowing frame to wholly downward position.

3. In combination with a door, a transparent panel member hinged to said door in an opening therein to swing downwardly and inwardly, a chain having one end fastened to said panel and other to said door allowing panel to swing to substantially horizontal position, and a barred frame extending across the said opening in front of the said panel member, said frame being hinged at its lower edge to the door to swing inwardly through the said opening, a iink pivoted atits upper endto the side of the said frame, a chain attached at one end to the door andat its other end to the link, and a locking bolt .carried bv said frame and adapted to engage the said door to retain the frame in upright position, said locking bolt,

passing through an aperture in the'said link to retain the latter in position lying along the said frame, to limit the inward swinging movement of the frame.

In testimony whereof I have affixed my".
